-LRB- CNN -RRB- -- Polygamist sect leader Warren Steed Jeffs , who is awaiting trial in southern Utah , was charged with eight additional felony counts from Arizona in two separate cases , authorities said Thursday .

Polygamist Warren Jeffs is facing eight additional counts related to alleged incest and sexual contact with a minor .

A grand jury indicted Jeffs May 10 on two counts of sexual conduct with a minor and two counts of incest for alleged incidents that occurred in 2002 , according to a statement issued by Mohave County Attorney Matthew J. Smith .

On Thursday , another grand jury indicted him on two additional counts of sexual conduct with a minor and two additional counts of incest . Those offenses took place in Colorado City , Arizona , in 2003 , according to the indictment .

Both indictments state that Jeffs , leader of the Fundamentalist Church of Jesus Christ of Latter-day Saints -LRB- FLDS -RRB- , committed the offenses `` as an accomplice . ''

According to Arizona law , sexual conduct with a minor is a Class 6 felony punishable upon conviction by up to a year in prison . Incest is a class 4 felony punishable upon conviction by up to 2 1/2 years in prison .

`` The cases involve two separate victims , '' Smith said in the statement . `` Mr. Jeffs will not come to Mohave County to face these charges or to have an initial appearance on them until his Utah case is resolved . ''

Jeffs , 51 , is awaiting trial in Washington County , Utah , on a charge of being an accomplice to rape by arranging the marriage of a 14-year-old girl to her 19-year-old cousin .

The trial initially was set to begin in April , but Fifth District Judge James Shumate postponed it earlier this year , and a new date has not been set . At the time , Shumate said the delay was due to `` recent information in the case , '' but he did not elaborate .

The judge in March refused a defense request to move the trial out of Washington County because of press coverage , but he said he may reconsider if attorneys encounter difficulty during jury selection .

Utah prosecutors say that because Jeffs forced the underage girl to marry , and therefore forced her to have sex with the adult man , and because Jeffs insisted she stay married , he is an accomplice to rape .

During his preliminary hearing in December , Jeffs ' defense attorneys said that he never knew whether the marriage he arranged was consummated and , if it was , whether the sex was consensual .

The girl , identified only as Jane Doe , testified at the preliminary hearing that she was `` so scared '' during the forced wedding .

`` The whole time I was crying , '' she said . `` I wanted to die . ''

The rape as an accomplice charge is a first-degree felony in Utah , carrying a penalty upon conviction of five years to life in prison .

Jeffs previously was charged in Arizona with two counts of sexual conduct with a minor for allegedly presiding over arranged marriages , along with an additional charge of conspiracy .

Those charges , from 2005 , were put on hold while Jeffs faces trial in Utah .

Jeffs was captured August 28 , 2006 , in a traffic stop near Las Vegas , Nevada . At the time , he had been on the FBI 's 10 Most Wanted List for months .

The FLDS freely practices polygamy in the towns of Hildale , Utah , and Colorado City , Arizona , which straddle the state line . The sect maintains groups of followers in Texas , South Dakota , Nevada , British Columbia and Mexico .

The offshoot sect broke from the mainline Church of Jesus Christ of Latter-day Saints , based in Salt Lake City , Utah , over the practice of polygamy .

The Mormon church , which gave up plural marriage more than a century ago , has no ties to Jeffs ' group . E-mail to a friend
